EXTMOS main objective is to create a materials model and the related user friendly code that will focus on charge transport in doped organic semiconductors. Its aims are
(i) to reduce the time to market of
(a) multilayer organic light emitting devices, OLEDs, with predictable efficiencies and long lifetimes
(b) organic thin film transistors and circuits with fast operation.
(ii) to reduce production costs of organic devices by enabling a fully solution processed technology.
Development costs and times will be lowered by identifying dopants that provide good device performance, reducing the number of dopant molecules that need to be synthesized and the materials required for trial devices.
(iii) to reduce design costs at circuit level through an integrated model linking molecular design to circuit operation.
Screening imposes the following requirements from the model
1. An improved understanding of dopant/host interactions at the molecular level. Doping efficiencies need to be increased to give better conducting materials. For OLEDs, dopants should not absorb visible light that lowers output nor ultraviolet light that can cause degradation.
2. An ability to interpret experimental measurements used to identify the best dopants.
3. The possibility of designing dopants that are cheap and (photo)chemically robust and whose synthesis results in fewer unwanted impurities, and that are less prone to clustering.
The EXTMOS model is at the discrete mesoscopic level with embedded microscopic electronic structure and molecular packing calculations. Modules at the continuum and circuit levels are an integral part of the model. It will be validated by measurements on single and multiple layer devices and circuits and exploited by 2 industrial end users and 2 software vendors.
US input is provided by an advisory council of 3 groups whose expertise complements that of the partners.

Organic thin-films constitute a fast growing area of electronic and opto-electronic devices that offer cost-effective and flexible solutions for e.g. improved energy efficiency and energy harvesting. Due to the achievements made during the past decade, the development of such sustainable energy devices has already reached an early commercialization stage, however, in order to further boost their uptake on the market, improvement of device efficiency and lifetime is still needed. Such improvement requires a profound knowledge about fundamental properties of thin-film hybrid interfaces and their implementation in devices a knowledge that is already requested from established and new companies focusing on organic electronic and opto-electronic devices. With this project, we establish a network that trains and educates young researchers within the area of hybrid thin-film interfaces for sustainable energy devices. In order to provide training and education that are of both high quality and of relevance for the market, the research training programmes are in this consortium based on a combination of state-of-the-art research and industrial development and production processes. The consortium consists of 5 full university partners, 1 research organization, 2 full industry partners, 4 associate industry partners and 1 associate research organization. The partners in the consortium are deliberately chosen in order to build up a unique cluster between universities and companies. Such cluster provides the young researchers in the consortium strong competence on 1) state-of-the-art research, 2) innovation and entrepreneurship and 3) large through-put industrial production processes. The training network combines expertise on modeling, thin-film formation, device fabrication and characterization (multidisciplinary aspect) in order to provide solutions for a range of different sustainable energy applications such as thin-film transistors and solar cells (intersectoral aspect).

The overall objective of the PHEBE project is to develop innovative, high-efficiency, blue emitters for white OLEDS, which will create a major breakthrough in the cost performance of OLED lighting. To produce the innovative blue emitters, two new types of molecular systems without rare earth complexes - will be investigated:
intramolecular charge transfer systems that enable thermally activated delayed fluorescence (ICT-TADF)
intermolecular exciplex charge transfer systems that enable thermally activated delayed fluorescence (Exciplex-TADF)
In order to develop the ICT-TADF and Exciplex-TADF based emitters, the following scientific and technical objectives will be targeted:
Objective 1: Screen potential ICT-TADF and Exciplex-TADF compounds with theoretical models
Objective 2: Synthesise the most promising ICT-TADF and Exciplex-TADF model compounds
Objective 3: Characterise and select the best ICT-TADF and Exciplex-TADF synthesised compounds
Objective 4: Design white stack units employing the selected TADF based emitter and block materials
Objective 5: Design close-to-production OLED lighting panel demonstrators
To show the projects overall objective has been achieved, white stack tandem units (2 x 2 cm2 with 90 nm ITO) and OLED lighting panel demonstrators (e.g. 25 cm2 circular panels) - based on the new blue emitters will be produced and tested that meet the performance targets indicated in the H2020 call ICT 29 2014.
The PHEBE project will be undertaken by a strong consortium of partners that span the complete value chain for the development and commercialisation of the new, high-efficiency, blue emitters for white OLEDS: OLED lighting research organisations (UDUR, TUD and KTU), OLED component producer (Novaled), and OLED lighting device manufacturer (Astron-FIAMM). Overall, the PHEBE consortium is well-balanced in terms of the number of industrial and academic partners as well as their geographic spread.
